Specification of Letters Patent.

Patented Feb. 8, 1910.

Application flied January 12, 1907. Serial No. 352,018.

To all whom it may concern:

Be it known that I, Gnome Huonns, British subject, and resident ofBolton-le- Moors, county of Lancaster, En land, have invented certainnew and usefu Improvements in Signaling Apparatus, of which thefollowing is a specification.

This invention relates to apparatus for use on railways or other laceswhere a telegraph or other form of apparatus is employed fortransmitting signals and is designed to provide means for automaticallyrecording all such signals both sent and received as a time stamp signalrecord, that is a signal record expressed in the time the signal wastransmitted.

The invention may be employed in connection with any signal cabins,stations, places or depots, from which signals are transmitted orreceived, or it may be employed in other ways or for any purpose.

The invention consists essentially in re cording apparatus by which thesignal as recorded is expressed in the time at which it was transmittedthereby recording as a single recorda time stamp signal recordcomprising both the signal and the time it was recorded. Thus a singlehell call or dash is expressed in time 5.20.2.

and a double bell call or two dashes The invention will be fullydescribed with reference to the accompanying drawings forming part ofthe specification.

Figure 1 is a plan of the complete apparatus. Fig. 2 is an elevationpartly in section showing the time type wheels C the armatures I) D thestriker pad E of the magnets and the recording paper G. Fig. 3 is a planof the clock work motor whici operates the time type wheels C. Fig. 4 isan elevation of same partly in section. Fig. 5 is a transverse sectionalelevation through the time type wheels 0. Fig. 6 is a plan of the clockwork mechanism which governs or controls the clock work motor shown inFigs. 3, 4 and 5 showing parts above the line mm Fig. 8. Fig. 7 is aplan of same showing parts below the line :v-w Fig. 8. Fig. 8 is anelevation of the same, partly in section. Fig. 9. is a plan of theclock-work motor which operates or carries forward the record paper G.Fig. 10 is an elevation of same showing the releasing mechanism.

Fig. 11 is a perspective view-of the mag nets B B the armatures D D thestriker pads E E and the mechanism for controlling and releasing themotor clock shown in Figs. 9 and 10.

The several parts of the apparatus are mounted upon a base plate A ofmetal or wood with frame plates a of the usual form employed withclock-work motors.

In broad outline the apparatus comprises two sets of electro magnets B Bto be placed in electric circuit with the signaling instruments thestriker-pads E E carried by the armatures D D of the magnets, time typewheels C operated by clock-work motor F, a record paper or record stripG operated or moved forward by a clock work motor H a predeterminedperiod of time after each signal stamped thereon, and mechanism forreleasing the clockwork mo- .tor H after each impulse of the magnets andpermitting it to continue in motion during the time determined upon. Theelectro magnets B B are provided with electric contacts or terminals bywhich they are comiected-"with signaling circuit or with any suitablerelay so that they are actuated by each impulse that is passed throughthe circuit. The armatures D D of the electromagnets are each providedwith a striker pad E E which extends to one side of the magnets.Adjacent to the electro magnets a set or sets of time type wheels C aremounted to rotate under the striking pads E E so placed that. when thearmatures are attracted downward the pads strike the wheels. The typewheels (1 comprise hour, minute and seconds wheels that is Wheels whichare inscribed on their peripheries with type or printing numeralsrepresenting hours minutes and seconds respectively.

The time type wheels C are driven by the The wheels C are mounted onhollow concentric spindles or sleeves 0 each wheel mounted on a separatespindle and driven at the other end by a corresponding tooth wheel C.Each type wheel C is secured at one end of its hollow spindle and thetoothed wheel C at the other, the latter being pref-.

erably mounted on a collar screwed onto the shaft and secured inposition by a lock nut. The tooth wheels C are driven by the springmotor F the shaft f being rotated thereby and the first of the toothedwheels C driven at. the desired speed by the pinion spring motor F shownin Figs. 3, 4 and 5.

' controlled by an escapement k.

f. The second tooth wheel C is rotated by the arm f the star wheel f andthe pinion f the star wheel f being rotated one tooth for eachrevolution of the shaft 1. The third toothed wheel is rotated by arm fthe star wheel f and the pinion f, the star wheel f being rotated onetooth for each revolution of the star wheel i. There are two sets oftooth wheels C correspondingly moved and these inturn rotate two sets oftime type wheels C one set of the latter for each magnet. The strikerpad E operated by the magnet B presses the record on one side of thetype Wheels C and the striker pad E of the other electromagnet Bimpresses the record from the other side of type wheels 0, and themagnets are so connected electrically that one magnet is influencedunder a message sent and the other magnet under a message received, sothat the messages sent are impressed on one edge of the record and themessages received are impressed on the other edge. These messages appearon the record in their proper sequence, as described below.

In order to equalize the load on the clock and give the same amount ofwork to the spring when all the wheels C are being rotated a scroll f"is mounted on the shaft f against which rests a spring lever f. At eachpartial rotation of the shaft 1 the lever f is raised until the armengages the star wheel i At the next movement of the shaft the levermoves down the face of the scroll f thereby assisting the rotation ofthe shaft f and equalizing the load on the motor. At the extremity ofthe shaft 1 is a second finger S, the movement of which corresponds withthe movement of the wheels C and C. It is preferred that thehand Sandthe wheels C C, should move six seconds or one tenth of a minute ,ateach movement. The shaft F of the motor-clock F drives throu h anordinary clock train minute hand and hour hand M. The spring motor Fonly acts as a motor to drive the time type wheels C and is controlledby a controlllng clock K which can be accurately regulated and whichperiodically releases an escapement F The clockwork mechanism K seeFigs. 6, 7 and 8 is of ordinary construction with a train of-wheelsdriving an eccentric k and The eccentric k oscillates the esca ementlever K and at each revolution an the eccentric la releases theescapement F and permits a corresponding movement of the spring mo-..tor F which the escapement F rotates half a revolution. The clock K isaccurately regulated so that the eccentric It makes one revolution every6 seconds or tenth of a minute thereby fpermitting the corres ondingmovement 0 the spring motor 14 to drive the time type wheels 0. Theescapement lever K may be withdrawn from engagement with the escapementF by a lateral movement bfy means of the lever is for the puro allowinthe motor clock F to run ree to set the w eels G and hands M and M. Arecord-pa r G is caused to ass over the time type w eels C between t emand the striker-pads E E so that at each impulse of the ma ets B B animprint from the wheels 1s made upon the paper strip G.

As described above the striker pad E is adapted to cause an imprint onthe record from one side of the type wheels and the striker pad E fromthe other side one magnet being adapted to operate under the influenceof messages sent and the other magnet to operate under the influence ofmessages received, so that all messages sent appear on one edge of therecord and all messages received on the other edge, the messages sentand received appearing in their pro r s uence.

T e rib n G is wound upon the drum H and is withdrawn therefrom acrossthe type wheels C onto a drum H driven by an su1table mechanismpreferably by a d iivin roller J provided with a tension roller anddriven b clockwork s ring or other suitable motor An ink rib on G iscarried forward with the record-paper G to give the imprint upon thepaper.

he spring motor H, Figs. 9 and 10, is separate from the spring motor Fand is released simultaneously with the impulse or movement of thearmatures D D consequent upon the signal and draws the record paper G.The sprin motor H is ermitted to run after each re ease for a efinitespace of time, to allow for a given movement of the record paper G. Itis controlled and released by an escapement lever N which is raised bthe lever n on the rocking shaft n the sha n being rocked by the lever nwith which an arm 01 or d on the armatures D D engages at each impulseand depression of the armatures. When the escapement lever N is raisedit releases the disk L which permits the motor clock H to start andcontinue'running until the lever N falls again and engages the disk L.The disk L is provided with a projection or tooth on its periphery withwhich engages a projection or stop pin n on the escapement lever N. Theescapement lever N is maintained raised for the desired period by thequadrant escapement h which is projected forward under the lever N by aspring each time the lever N is raised thereby preventing the return ofthe lever N to normal position until the quadrant escapement it has beenwithdrawn. The disk L is rotated by a worn wheel h and worm h and on theworm spindle is mounted a retarding fan It to revent too high a speed.On the s indle 0 the worm wheel h a disk or scrol h with a signal iscompleted.

single tooth h is mounted. When the escapement quadrant h is projectedunder the escapenient lever N the tooth lr" at each revolution moves itback the distance of one tooth until the lever N drops off it intonormal osition shown in Figs. 10 and 11. The scroll h raises the lever Nas the tooth it engages the teeth of the escapement h.

it is obvious that any other suitable form of stop motion or escapementmay be applied to the clock-motor H. The worm wheel h and its shaft aredriven by an ordinary clockwork train as are also the roller J and drumH. A uniform intermittent feed is thus given to the record paper G. Theink-tape G travels between the record-pa er G and the type wheels C andis wound o the drum R onto the drum R by the spring motor H.

When a signal is transmitted one of the electromagnets B or B isenergized and attracts the corresponding armatures D and D and causesthe striker-pad E or E to press the record-paper G against the inktape Gand the time type wheels C thus stamping on the record paper G the timeas indicated by the wheels. The movement of the armatures D and D at thesame time depresses the lever n rocks the shaft 11/ and raises the lever11. thereby lifting the escapement lever M releases the clock motor Hand the record paper G is thereby traversed across the time ty e wheelsC. A fresh surface of the record under the striking pads E for the nextsignal. The time feed of the paper is governed by the quadrantescapement which permits a predetermined travel or feed after each Asthe motor clock F is released every 0 seconds or ten times every minuteand the time type wheels C are correspondingly moved the time on thewheels G to be recorded on the record-paper as a time stamp signal willbe altered 10 times every minute which is a division of timesufficiently fine for the purpose of record.

A signal is expressed on the record paper G by the position of the lineof numeralsindicating line-and the number of such lines of numerals, oneoperation printing and recording both the signal transmitted and thetime thus A single bell call or a dash is expressed in time in a singleline A double bell call or two dashes is expressed in time in two linesA treble bell call with at ease between the second and third signal cais is expressed in turn in two lines, a space and a single line 5.40.6.The following table is inserted as an expaper G is then brought ample ofa length of the recording paper G showing the signals recorded thereonthe messages being decipher-ed in the margin.
